DEVICFGR FOR'MING GLASS CYLINDERS.

To all whom may concern:

Be it known'tha't I,"FERDINAND J. HoUzE,

a citizen of't-he United States of America,A

residing at Grand Rapids, in the county of Kent and State.of Michigan, have invented certain new andusef'ul Improvements in Devices for Forming Glass Cylinders; and I do hereby declare the 4following to be a full, clear, and exact description of the invention, such' as will enable others skilled the art to which it appertains to make and use the saine.

My invention relates to improvements 'in' devices; for forming glass cylinders'for inak- `ing window glass yand like purpose s,'and its obJect is to provide a device that will form acylinder of uniformithickness throughout ;4

to provide .means for maintaining uniform temperature lof the melted glass.; to provide means for preventing too rapidly cooling of the cylinder when formed; a'nd'to'provide the device with` various new and useful features 'hereinafter more fully described' and particularly' pointed out in the claims.

Reference is had to the accompanying Figure l is a vertical section' of the device embodying my invention: Fig. 2 the' saine with the cover removed, and as it appears when in operation: Fig. 3 a plan view ofthe part of the' device shown in Fig. 2.

Like numbers refer to like 1 represents the tank in which the glass -is melted, the saine being provided' with 'I an horizontal portion of the passage l 'in the ing which opening and spaced apart there-v upper wall of which bottom is a number of openings 5 through which the melted glass may pass into the upper part of. the pot 6. Above this pot is the top ofthe casing 3,

which ishorizontally disposed and has a cir cular opening? above the pot 6, surroundfrom a short distance, are a .series of small openings 8.

"9 is a cover Iadapted to close allhof the Y openings in the top, in the center of which parts in all of l j 2. A device cdver is an opening 10 whichaifords a draft v for the escape ofa portion of the heat from the burner 12 placed below the pot 6.

'13 represents Vthe fluid glass, which in the process of producing glass cylinders,4 is drawn upward as at 14: through the opening 7 by any ofthe 'well known means. `The heat an'd flame from the burner'12 escaping through the openings'S surrounds the cylinder and niai'ntains the temperature thereof sufficient to prevent too sudden cooling.

.11 is an opening by which the device may -be connected Iby a suitable. pipe to a chimney or stack, if preferred..

In operation, the melted glass passing downward and thence laterally inthe passage' LI-is exposed to the heat of the burner 12 and preventedl from cooling therein and thence 4flows'upward through the opening 5,

being thereby uniformly distributed in the pot 6 and its temperature uniformlymaintained therein bythe flames from' the burner l2 surrounding saidpot. By this construction andthe consequent uniform tempera, ture of the' glass inthe pot. 6, the cylinder 14 will be of substantially uniform thickness throughout and will' be cooled slowly, `the heat of said cylinder being maintained as it slowly rises by means of the Haines escaping through the openings 8.

What 'I `clair is 1. A device 4or forming glass cylinders,

comprising ya melting tank, a pot near the same and communicating therewith by a side "opening .and a passage extending downward at the side of the pot next the tank and thence beneath the potwhereby the pot is heated at one side only by thetank and incoming glass, said pot being. also provided Vwith one vor more bottom openings to admit Ythe glass 'to that part onlyof the pot which is not so heated, whereby the heat' is rendered more uniform throughout the glass .-in: the

pot. l

for forming glass cylinders, comprising a -melting tank having i .side opening, a jacket having aside opening to receive the melted glass-and also having a top provided witli'al central opening and series of small' openings;concentric. therewith,

' anl inner p t having a downward and horizontally' extended passage to 'receive the glas`s,-. and openingsin'the upper wall of said passage t'o permit the glass to pass Ainto said pot, and means for applying heat toO l adapteito close the openingsm said top 15 and having a central opening, the cover also' .the inner pot.
